To buy a Xiphos sword, start by researching reputable sword makers or historical weapon retailers specializing in Greek replicas. Choose between decorative or battle-ready versions, depending on your needs. Check the blade material—high-carbon steel is best for functional swords. Look for authentic features like a leaf-shaped blade and secure tang construction. Read reviews, compare prices, and confirm return policies. Always verify the seller’s credibility and craftsmanship quality.
